After the initial flash of a K26 build, you can upgrade to K26 mega build or K3X mega (broadcom_K3X folder). K3X mega is the recommended build version for this router, and supports SFE accelerated NAT after build 33006.

As is explained in Wireless-N Configuration make sure that you use AES with WPA2 security for your wireless N network. Do not use TKIP or the wireless speed will revert to the g standard and that would be a pity. (AES+TKIP is also allowed but not recommended.)

It is recommended to set:

2.4 GHz radio to "NG-Mixed".

5 GHz radio to "NA-Mixed".

Both 2.4 and 5 GHz Radios run at a stock transmitting power of 100mW. Decreasing the transmitting power to a value between 40 & 50mW may help stability, especially if the router has poor cooling.
